As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory proudly presents our PE Membrane Filter Cartridge designed specifically for pharmaceutical water injection systems. With a precision 0.2 micron rating and a 10-inch length, this cartridge ensures reliable removal of bacteria, particles, and endotoxins, meeting the stringent requirements of sterile filtration in pharmaceutical production. Backed by our annual export value of US$5-10 million and global shipping from major ports like Tianjin and Qingdao, our product delivers consistent quality to markets across North America, Europe, and Asia.
This filter cartridge is engineered with a high-performance polyethylene (PE) membrane that provides excellent chemical compatibility and low extractables, making it ideal for critical applications such as water for injection (WFI), pre-filtration, and final sterilization. The 222 O-ring end cap ensures a secure, leak-proof seal in standard 10-inch housings, while the robust construction withstands repeated steam sterilization cycles. Every cartridge undergoes strict quality control to ensure consistent pore size and flow characteristics.

Frequently Asked Questions
-
Q: What is the difference between 0.2 μm and 0.45 μm membranes for water injection?
A: 0.2 μm filters are considered sterilizing grade, removing all bacteria and most endotoxins. 0.45 μm are typically used for clarification or pre-filtration. For WFI final sterilization, 0.2 μm is required. -
Q: Can this cartridge be used with hot water (80°C) continuously?
A: Yes, our PE membrane filter cartridge is designed for continuous operation up to 80°C. For steam sterilization, temperature can reach 121°C for short cycles. -
Q: Do you provide integrity test data with each cartridge?
A: We offer forward flow or bubble point integrity testing as a value-added service. Please specify your requirement when ordering. Standard cartridges are shipped with a certificate of compliance. -
Q: What O-ring materials are available?
A: Standard is silicone. Optional materials include EPDM, Viton, and PTFE encapsulated. Contact our sales team for compatibility with your specific chemicals. -
Q: Is the PE membrane hydrophilic or hydrophobic?
A: Our PE membrane is hydrophilic, allowing easy wetting with water, which is essential for low-pressure drop in aqueous filtration. -
Q: What is the typical flow rate for a 10-inch 0.2 micron cartridge?
A: Flow rate depends on pressure and viscosity. Typically, at 1 bar differential pressure with water at 25°C, a single 10-inch cartridge can deliver 20-30 liters per minute. Actual performance may vary based on system design. -
Q: Can you provide a sample for evaluation?
A: Yes, we offer sample cartridges for qualified buyers. Please fill out the inquiry form or contact our sales department to discuss your needs. -
Q: How do you ensure the quality of the filter?
A: We follow ISO 9001 management system (certification available upon request). Each batch is tested for bubble point, flow rate, and integrity. Our factory has been operating since 1998 with a strong focus on quality control.
